Relations among Muslims, Jews, and Christians have been shaped not only by the theologies and beliefs of the three religions, but also, and often more strongly, by the historical circumstances in which they are found. As a result, history has become a foundation for religious understanding. In each historical phase, the definition of who was regarded as Muslim, Jewish, or Christian shifted, sometimes indicating only a religious identification, but more often indicating a particular social, economic, or political group.
While the tendency to place linguistic behaviour, religious identity, and cultural heritage under one, pure definition has existed for a very long time, our modern age with its ideology of nationalism is particularly prone to such a conflation. Ethnic identities have sometimes been conflated with religious identities by both outsiders and insiders, complicating the task of analyzing intergroup and intercommunal relations. For example, Muslims have often been equated with Arabs, effacing the existence of Christian and Jewish Arabs (i.e., members of those religions whose language is Arabic and who participate primarily in Arab culture), ignoring non-Arab Muslims who constitute the majority of Muslims in the world. In some instances, relations between Arabs and Israelis have been understood as Muslim-Jewish relations, ascribing aspects of Arab culture to the religion of Islam and Israeli culture to Judaism. This is similar to what happened during the Crusades, during which Christian Arabs were often charged with being identical to Muslims by the invading Europeans. While the cultures in which Islam predominates do not necessarily make sharp distinctions between the religious and secular aspects of the culture, such distinctions make the task of understanding the nature of relations among Muslims, Jews, and Christians easier, and therefore will be used as an analytic tool in this chapter.
